BTW, @op , if you are getting Nexus, try not to update the phone to 4.3 , and if you do, be ready to face the battery drain caused by charger ( USB or AC - Unless you hit a reboot everyday or it won't Deep Sleep ) , This main root of this problem is the kernal which can be improved by qualcomm update but Google hasn't implemented yet on the current update, but there are custom Kernal like the Franco kernel which has addressed the issue, AFAIK. Do correct me ( if there are experienced members here with that knowledge ) if I'm wrong with this.

Camera is good but it's not as good as S3/S4/S4 mini that's all, just giving him a heads up.

I would say the Indian Nexus 5 will have a 4G radio inside it as its's highly unlikely LG/Google will make a version of Nexus 5 for India which does not have a 4G radio.
But, even though 4g radio might be present, it might be disabled by the firmware as India does not have LTE for phones yet (only for data card)

Even if we can enable the 4g option by flashing another ROM, it would be useless in India for the forseeable future as our LTE spectrum is on the 2300 mhz band, which is not used widely afaik (and I think this is the reason 4g is only available on data cards as I have not seen phones with a 2300 mhz 4g radio) ;

the international version of nexus 5 has the following LTE bands: 800 / 850 / 900 / 1800 / 2100 / 2600 - so 4G will not work on N5 in India as of now.
